METHOD FOR THE RAPID PRODUCTION or WOODEN PANELS AND THELIKE.

FROM MILL CLIPIPINGS Application filed April 18, 1925. Serial No. 24,142.

This invention relates to a novel method for the rapid production of wooden panels from mill clippings and the like, enabling mill refuse to be recovered and usefully employed in the manufacture of wooden articles which ordinarily are made only from dimension lumber.

More specifically, my improved method pertains tothe manipulation and arrangement of a plurality of clippings in the form of a board or panel in such manner that the work can be done with great rapidity and inexpensively, andthe panel when finished will not disclose end wood glued jointsthat are of sufiicient length to show objectionably through a veneered surface which may be later applied to the panel.

As is well known, if two pieces of wood of considerable width are glued together end to end, so as to form a relatively long end wood joint, that joint is apt to be observable on the polished surface'of the finished veneer, but if the end wood joints are short it is not likely to occur. Therefore, one of the objects of my invention is to avoid long end wood joints in the finished panel and still secure rapid production.

My improved method, while being capable of being carried out by hand, is also workable by suitable automatic machinery. It is admirably adapted for the economical reclaiming of small pieces, say, fifteen to twenty square inches area, and of longer and narrower strips which ordinarily are disintegrated and used in the manufacture of molded articles, or burned.

The rapidity with which panels can be built up according to my method, and the strength and smoothness which the finished panel possesses, as well as the absence of long end wood. glued joints, is due to my present method of manufacture, which will now be described.

Mill clippings and the like are received in large quantities and consist of end clippings, side trimmings from boards, and

when the pieces of any one lot are placed end to end they will make roughly a board-- like structure.

In the drawings, Fig. 1 shows a plurality of clippings which have been sorted asyto the width of goodmaterial in them.

Fig. 2 shows the same parts after their adjacent edges have been trimmed to fit one with another. i

- Fig. 3 shows the same parts glued together end to end, forming a board-like structure having uninterruptedtransverse joints.

Fig. .4 shows the same parts after having been ripped into a plurality of longitudinal strips.

Fig, 5 shows the strips secured together to again form a board-like structure having finished panel of long end wood joints, these a uninterrupted transverse oints are made into interrupted joints, as shown in Figs. 5 and 6, by first cutting the board lengthwise into a plurality of parallel strips, as 3, 4 and 5. This is preferably done by ripping with gang saws. The several strips are then reassembled and secured together to again form a board-like structure, but this time with staggered or interrupted transverse.

j oints.

This may be conveniently done by H endwise displacement of one strip 4 with re glued joints extending lengthwise, while the transverse'joints areroverlapped by the adacent solid pleces, thus giving great strength to the finished panel, although the panel may have-been made of very small clippings or strips.-

A given lot of clippings can by this method be easily fabricatedinto a plurality of boards of various Widths andot any d'esired length the Widen-0f such boards in themselves constituting panels; or a number of such boards glued together comprising'a wider panel.

Such panels are suitable for all the pur- 7 poses toWhich panels made-from commercial lumberare adapted, such-as furniture,

phonograph and radio cabinets andthe like.

Having thus described my invention, What I claim and-desire to secure by Letters Patcut is: I r

1. The herein described method' o'l' manufacturing. panels from clippings, consisting in first securing together end to end-'a plu rality of. clippings. to form a" board-like structure comprising a single layerofunate rial having uninterrupted transverse JOlDlJS then cut-ting said layer-lengthwise" into a plurality'oi strips and finally securing said strips together along their longitudinal:

edges vto again :torma board-like structure comprising a layer of material having inter-- ruptecl transverse o1nts.

'2. The herein described method of manu tacturing panels from clippings,consisting infirst gluing together end to end plurality of clippings to form a board-like structure comprising: at single layer of material having uninterupted transverse joints, then cutting said layer lengthwise into a; plural-- ity ofparallel sided strips-and finally gluing said strips together along their longitudinal edges toiiagaini'l orm aboard-1i e structure comprising a layer of material having interrupted transversejoints.
